         10 . The wearable air purification system as claimed in  claim 1 , wherein each of the left and right side motor housings is positioned remote from the air delivery region so as to locate rearward of the ears of the user when the wearable support is supported on the head in use. 
     
     
         11 . The wearable air purification system as claimed in  claim 10 , wherein the motor housings define a gap between them at the rear of the user's head, when the wearable support is supported on the head in use. 
     
     
         12 . The wearable air purification system as claimed in  claim 1 , wherein the left and right side supports connect to one another, or are formed integrally with one another, at the rear of the user's head so as to define a closed loop structure with the air delivery mask. 
     
     
         13 . The wearable air purification system as claimed in  claim 1 , wherein each of the left and right side supports includes a recess which exposes a respective left or right ear of the user when the wearable support is supported on the head in use. 
     
     
         14 . The wearable air purification system as claimed in  claim 8 , wherein each of the left and right side bridge sections includes a recess which exposes a respective left or right ear of the user when the wearable support is supported on the head in use. 
     
     
         15 . The wearable air purification system as claimed in  claim 1 , further comprising an audio device mounted on each of the left and right side supports, each of the audio devices being configured to deliver audible sound to a respective ear of the user. 
     
     
         16 . The wearable air purification system as claimed in  claim 1 , wherein the air delivery mask is slidably mounted relative to the left and right side supports. 
     
     
         17 . The wearable air purification system as claimed in  claim 1 , wherein each of the left and right motor housings houses a motor-driven impeller to deliver a respective one of the left or right side air flows to or away from the air delivery region. 
     
     
         18 . The wearable air purification system as claimed in  claim 1 , further comprising a filter associated with each of the left and right side motors for filtering the air flow.
